Interlaken Town standing, high SDWIS violation third
350 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 16% is middle-third health share (≤ 23%).
The verdict
Interlaken Town sits in the upper third of the sitemap cohort by violation count (178), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (350; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 16% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
